SHOE-HEEL.

Specification of Letters Patent.

Patented May 5, 1914..

Appiication fuea pra 12, 1913. seriai 110.7611581.

To all whom it may concer/n Be it known that I, FRANCIS A.'NoLAN, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented a new and use-v ful Improvement in Shoe-Heels, -of which the following is a specication.

An object of this invention 1s to provide ari-improvement vin fasteners for detachable heels, whereby the fastener can bereadlly positioned on a shoe to receive a heel made of rubber or other resilient material and hold it firmly in position so that itcannot become unintentionally detachedand at'the said time permitting the ready removal of the heel when desired for purposes of interchanging and prolonging the life of heels or renewing them.

More particularly this invention 1s an 1mprovement upon the construction set forth 1n Patent Number 1,001,879, granted" to me on October 3rd, 1911, for heel fasteners.

Among the advantages attained by my 1nvention over priorconstructions arethe 1m proved manner in which the resilient detachable heel i mounted upon the fastener and the heel secured to the shoe and the particular means provided for assisting in positioning the resilient detachable heel and its fastener upon the shoe.

Further advantages attained by my .invention will be pointed out in the following description.

In the accompanying drawing forming art of this specification, Figurel is a plan ooking down upon my improved resilient heel with my improved fastener in place therein; Fig. 2 is a section taken upon the line A--A of Fig. 1; Fig'. 3 is a perspective of my improved heel with the fastener removed; Fig. 4 is a section taken upon the line B--B Fig. 1; Fig. 5 is a detail of a shoe partly in section showing my improved heel and fastener mounted thereon, said heel and fastener being illustrated in section upon the line C-C, Fig. 1; Fig. 6 is a longitudinal central section of an alternative construction of my invention and Fig. 7 is a perspective of the heel illustrated in Fig. 6 with the fastener removed.

In the drawing is illustrated a portion of a shoe D having a counter 2, sole 3 and a heel base 4, which may be of any desired thickness or may be omitted entirely. A heel E formed of rubber or other suitable resilient material is adapted to be attached to the shoe by a fastener Fv for. which the heel E is suitably recessed at G. The fastener F .is in the form of a plate 5 punched from a flat piece of'sheet metal having forwardly and rearwardly rim portions 6 and 7 which are adaptedtobe bent-upwardly at right angles to the plane of the plate. At the corners ofthe upturned portions are acute marking points 8 which extend upward in' the completed form of the device as shown in Fig. 2, and having one face 9 oblique and o-ne face 10 normal to the surface of the heel base. From the lateral sides of the plate 5 extend rim portions 11 and 12. -These side rim portions are at right angles to the plane of the surface of the plate and are formed with spaces or openings 13 and 14 between them through the body of the plate which in turn produce a bridge 15 connecting the forward and rearward ends of the plate for remforcing purposes. Holesl 16 are punched in the plate 5 through which nails 17, screws or other suitable means of attachment for the shoe may be passed. The rim portions 6, 7 11 and 12 are of substantially the same height above the plate and form a rimwhich is adapted to rest against the lower surface of the heel base 4 of the shoe on its middle line with the bridge 15 downward.

n From the lateral sides of the plate pro- ]ect iianges 18 and 19 extending from the forward to the rear ends of the sides. These flanges are formed with rounded sides and lie adjacent to each other with a V shaped opening 2O in each iiange between its ends. In this position the nails 17 are driven upward through the holes 16 and heel base'and attach the fastener firmly' to the shoe. The points S are adapted to be fixed in the leather of the heel base 4e and assist in serv ing to take the lateral strain from the nails 17. The nails 17 together with the points 8 are strong enough to'resist all of the usual stresses of a rubber heel attached tothe fastener F when in service.

The heel E has the usual outer design which together with the heel base 1 make up a heel of the proper height for a shoe. In the top of the heel is the cavity G fitted to the exterior of the rim formed by the rim portions 6, 7, 11 and 12 and fitting snugly over them when the heel E is in its proper position on the shoe. Below the top of the heel the cavity G is recessed laterally to receive the anges 18 and 19, the resilient material being left in the form of a web 21 to lill the lV shaped space between the flanges on each side of the fastener. The flanges 18 and 19 beingof the same form on the two sides of the fastener, the recesses in the resilient heel E are of the same form on the two sides of the heel, and the heel may be put on from either side equally well, which prevents the delay and possible injury'7 to the heel from putting a heel on wrong on to .an unsymmetrical fastener, and also permittingheels on a pair of slices being interchanged to produce even wear and longer life. The bottoni of thev cavity G in the rubber heel is formed with protuberances 22 and 23 equalizing in height the thickness of the plate 5. These prot-ulnrances are similar in/ shape to the spaces or openings 13 and 1linlfthe plate and serve to strengthenthe en.:

i gagement between the resilient heel and the fastener and prevent all longitudinal and ateral movement between said parts. Thus the heel on its mountingis strengthened materially over a. construction wherein protuberances of the character set for th are not provided between said parts.

Thenpper surface 24 of the heel is con- Cave` its marginal edge 25 around the entire heel lying in a single plane. This concavity i causes the marginal edge to lie vin the same plane with the extremities of the points 8 thus enabling the heel E to be placed lupon 4 the portion 4. to mark the position of the fastener which is inserted in place. -When so ,positioned a sharp impact against the lower surface of the detachable heel causes the points 8 to indent the lower surface of the heel base 4. After marking the position of the fastener -on the heel base, the fastener is removed from the detachable heel and secured in position according to said indentations on the heel base by the nails 17 and the detachable heel is then sprung into position on the fastener. The detachable'heel is thus adapted to be secured in place under tension or compression causing a firmer hold by suction upon the heel base and forniing a tighter joint between it and the base. his is obviously an advantage because the mounting is stronger and the joint neater in appearance, not allowing any moisture or foreign matter to creep into the cavity G.

In the alternative construction the fastener 26 is of substantially the same design as the preferred, excepting that it is made out of east material instead ot heilig stamped from a plaie. 'the protubcrauccs instead of being formed in the dctznhalilc heel aire ot single form produced on the lower surface ot' the fastener 26 and the heel formed with a space or depression 27, the margin of which fits snugly over the margin of the protuberance 28 on the fastener.

1n accordance with the atent statutes I have described the principiles of operation of my invention together with the apparatus which l now consider to represent the best embodiment thereof but .l desire to have it understood that the construction shown is only illustrative and that the invention can be carried out by other means and applied to uses other than those above set forth within the scopeof the following claims.

Having described my invention, what I claim as ne and desire to protect by Letters Patent is:-

1. A fastener for a resilient shoe heel comprising a body having a rim portion to space it'froi'n the heel of the shoe and a flange projecting laterally from said body, in combination with a recessed resilient heel arranged to be sprung over said body and tlange to engage with the same, one of said parts having a protuberance and the other an opening in which said protuberance is arranged to engage to assist in preventing lateral displacement of said heel from said body.

2. In combination, a fastener arranged to be permanently attached to a shoe and having means for separately engaging a resilient shoeheel'and integral marking points to positii n' said fastener on the shoe, a resilient heel in which said fastener is engaged having a concave face lying adjacent the shoe, the rim of which being arranged as regards the extremities of said points to prevent said points normally engaging the surface of the heel is detachably secured over said permanently attached fastener on said shoe.

In testimony whereof, I have-s1gned my name to this specification in the presence of two subscribing witnesses.
